影响版本:
phpMyAdmin phpmyadmin 3.x
phpMyAdmin phpMyAdmin 2.11.x
漏洞描述:
BUGTRAQ ID: 32720
phpMyAdmin是用PHP编写的工具，用于通过WEB管理MySQL。
phpMyAdmin的./phpmyadmin/libraries/db_table_exists.lib.php文件中没有正确地过滤table参数：
$_result = PMA_DBI_try_query(
'SELECT COUNT(*) FROM `' .
PMA_sqlAddslashes($table, true) . '`;',
null, PMA_DBI_QUERY_STORE);
PMA_sqlAddslashes()函数仅禁用了单引号，但忽略了反勾号（`）和双引号（"），因此远程攻击者可以通过提交恶意请求执行sql注入攻击。
